- 34 - IMPROVED COMPOSITE SEPARATION MEMBRANES AND THE PREPARATION AND USE THEREOF Abstract of the Disclosura Composite membranes are post-treated with a volatile solvent system, with or without minute amounts of additives therein, to repair defects in the thin separation layer thereof. The membrane is then dried by the evaporation of said solvent. Minute amounts of non-volatile additives remain in and plug imperfections in the separation layer thereby enhancing the separation, and the overall separation/permeability, characteristics of the composite membrane.
